I have no experience with Unity, but i do have some experience in game development and i canot help but feel like that sounds awefully optimistic, sorry.I just used the Diablo example as a base. To make things good, it would need a lot more indeed. But it is within the possibilities of what the game can do I think. WoW has a lot more assets than Diablo so there can be a lot of world building possible, even if procedural. I don't know if you know Unity 3D (the game engine)? There is a tool that allows devs to have presets used in procedural generation. For example, if you want an Argus timeline set in Mac'Aree before Sargeras, you can have a few presets of villages, hubs and stuff. They will always be different, but each zone will have one. You can have dynamic events : in the middle of the timeline, the Legion invades and through shaders and zone effects, you add a bit of depth. The next time you visit this timeline, it can be the Void, giving the zone a completely different feel.
Yes, that was the downfall of Torghast. This type of content should be completely independant from the main game. It can have its own self contained progression path, but you shouldn't need it to raid or quest or whatever else. I too miss the iteration. It feels like nowadays, they abandon features rather than cut the parts that didn't work and build on top.
I disagree completely ahah. The game needs to reduce the hegemony of the holy trinity (Raids / Dungeons / PvP). A huge chunk of the playerbase have no interest in those activities. I barely touch them, resulting in me taking long breaks. If there were more side activities set in this world, I would play much more. I love the RPG part of the game so having a game mode that I can explore to experience parts of the lore or fun What if scenarios.
Even better if this game mode isn't made stupidly easy in a patch or two.
What's the point of adding new raids / dungeons that will start collecting dust a few months after their release?
Questing needs to be reworked, evergreen systems, more solo activity (that can be done with friends for those who don't like to play alone).
(If I misunderstood what you meant, let me know.)
And it would be devastating if it went wrong.
